There are a number of locally available materials that yield gold, silver, and platinum when refined. You may not yield the best results the time you do it but refining of precious metals tend to be very easy and one does not need any experience. One would only need the right equipment, supplies and definitely the right information so as to refine precious metals. Among the materials one can refine as an individual include electronic scrap such as circuit boards, CPUs, RAM, pins among other components. It would also be possible for one to rely on coins, jewelry and bullion as well in his or her refining of precious metal. In addition, one would need to use the catalytic converter to refine platinum metals as well. It would also be possible for one to refine precious metals by utilizing of gold nuggets, black sand or even jeweler waste. It would also be modest for one to know that it is possible for one to refine silver from the x-ray film.
One would also need to make sure that he or she gets the procedure right even when he or she has the right tools. One would need to know that he or she may need salt water or with acid. It would be modest for one to note that both salt and acid tend to work perfectly well when it comes to playing their roles in refining precious metals. Where one refines the metals for himself or herself, he or she would be sure that he or she would minimize cost, be sure of safety and also be sure that he or she will get what he or she wants. One would need to use either the electrolytic or the chemical process. One would need to use dilute nitric acid where he or she opts to use electrolytic way but would expect little fumes.
Apart from the material from where one is to extract gold, one would only need salt water. One would only need to hang the metal with the wire and then connect the wire in question to the car battery charger. Where one does not do that, he or she would need to make sure that he or she uses a related unit. One would then turn on the current through the wire and then into the acid. The metal tends to dissolve at a rate of about an ounce every hour.
One would also need to make sure that he or she has a precipitant such as quadratic. Pure gold tends to turn into solid metal with all other metal impurities remaining dissolved. One would also need to know how to refine gold with acid a method traditionally known as aqua regia or royal water. One can easily learn more about refining precious metals where he or she visits a reliable website for more.
